Why Do My Lights Flicker When My Furnace Turns On?

If you’ve noticed that your electricity flickers when you turn the furnace on, it could be a sign of a larger issue. It’s a good idea to contact an HVAC professional right away to inspect and repair your furnace. If your lights frequently flicker when you turn the furnace on, it could mean:

  • The circuit is overloaded: Your home’s electrical panel is full of circuits, and many of them supply power to more than one electrical appliance at a time. When your furnace turns on, any light fixtures that are running on the same circuit as the heater could flicker because their electricity supply is briefly lowered. In this case, you would need to ensure that your heater has its own circuit and breaker. Contact Comfort Services to inspect your furnace and check for a circuit overload.
  • The wires are exposed: All wires should be fully encapsulated with sheathing. If the wires on the on the furnace’s power cord are exposed, this can cause electricity to skip from one wire to another and can start a fire. If you notice any exposed wires, be sure to contact an electrician right away to prevent any serious damages.
  • The distribution panel is overloaded:  Every home has a maximum amount of voltage that can be safely supplied to the structure through the distribution panel. When you add too many circuit breakers or major appliances to your home, you could overload the panel.  

To ensure your safety and comfort, you should always contact an HVAC expert if you have concerns about the condition of your furnace. It benefits you in the long-run to have your furnace properly inspected, maintained, and repaired throughout the year. Contact Comfort Services for all your furnace repairs and questions.
